. check error handling/cleanup paths
. add drm_plane / overlay support
. add video decode/encode support (via syslink3 + codec-engine)
. still some rough edges with flipping.. event back to userspace should
really come after VSYNC interrupt
. where should we do eviction (detatch_pages())? We aren't necessarily
accessing the pages via a GART, so maybe we need some other threshold
to put a cap on the # of pages that can be pin'd. (It is mostly only
of interest in case you have a swap partition/file.. which a lot of
these devices do not.. but it doesn't hurt for the driver to do the
right thing anyways.)
. Use mm_shrinker to trigger unpinning pages. Need to figure out how
to handle next issue first (I think?)
. Note TTM already has some mm_shrinker stuff.. maybe an argument to
move to TTM? Or maybe something that could be factored out in common?
. GEM/shmem backed pages can have existing mappings (kernel linear map,
etc..), which isn't really ideal.
. Revisit GEM sync object infrastructure.. TTM has some framework for this
already. Possibly this could be refactored out and made more common?
There should be some way to do this with less wheel-reinvention.
. Review DSS vs KMS mismatches. The omap_dss_device is sort of part encoder,
part connector. Which results in a bit of duct tape to fwd calls from
encoder to connector. Possibly this could be done a bit better.
. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
access is made from any component in the system. Which means on suspend
CRTC's should be disabled, and on resume the LUT should be reprogrammed
before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
buffer mapped in DMM/TILER before LUT is reloaded.
. Add debugfs information for DMM/TILER
